The Sustainability Innovation Index was built on a simple observation: the science exists, the capital exists, the consumer demand exists, and the innovations exist — but they don’t always find each other. This platform exists to close that gap.
SII is not neutral. It was developed by people with a direct stake in seeing the sustainability innovation ecosystem function well — researchers who need capital to follow the science, investors who need real signal amid noise, innovators who need to find their market, corporations who need to meet their commitments, and consumers who deserve to trust what they buy. The honesty of that self-interest is part of what makes this tool credible.

🔒 Our integrity commitments
1
Verified sourcing only. All database entries are curated from named, identifiable organizations. Web intelligence is attributed to tier-1 sources — never anonymous, never fabricated.
2
Transparent uncertainty. Every intelligence item carries a confidence rating. We flag what we don’t know. We’d rather say “verify this” than overstate certainty.
3
Editorial independence. No entry is purchased. No company pays for inclusion or prominence. The database reflects research quality, market activity, and scientific relevance — not advertising spend.
4
Community review with curatorial gatekeeping. Submissions are welcome. Nothing is added without human review and evidence verification. The database grows by quality, not quantity.
5
Named self-interest. We are not neutral observers. We believe the sustainability innovation ecosystem needs to function better, and we built this tool because we have skin in the game — as do our partners.
